I have an idea:
-A brash, tomboyish pegasus♀ tinkerer with an attitude problem who is a total horndog. Also, she has heterochromia.
-A rich, snooty but adventurous otokonoko unicorn♂ chef who has a library’s worth of information and whose parents are never home.
-A loud, obnoxious kirin♀ with schizophrenia who constantly does weird things and has an obsession with using pastries in her attacks. She also has a phobia of squirrels.
-An earth pony♀ amazon from an abusive family who has trust issues and social anxiety and wants to become a fashion designer.
-A devout and religious flutterpony/melowy♀ who is really tall, a lesbian, and a combat medic.
-A jock batpony♂ who is openly gay and enjoys playful teasing, but was once beaten up for choking in a sports game and lost his old friends.
-A nerd zebra♂ who tries to think and act logically and rationally to a fault, and is really endowed.
-A hippy kelpie♂ who’s openly a nudist and talks like he’s stoned all the time. Very philosophical, as well.
-A ♀ brobdingnagian of undecided race who’s British AF and wants to travel the world.
Wait, those are all characters from my original IP. Oops.
